Specication of Letters Patent.

Application i1ed March 19, 1921. Serial No. 453,768.

T 0 all whom t may concern.'

Be it known that l, Ennio M. ANDERSON, a citizen of the United States,residing at Kansas City, in the county of lVyandotte and State ofKansas, have invented a certain new and useful improvement in PumpDrains, of which the following is a speciiication. n

My invention relates to improvements in pump drains.

The object of my invention is to provide a novel means for draining apump to,pre vent its freezing.

A further object of my invention is to provide novel pump draining meanswhich is simple in construction, cheap to make, durable, and not liableto get out of order, which may be readily applied to pumps now in use,which is easily operated, and which is efficient in operation.

The novel features ofpmy invention are hereinafter fully described andclaimed.

In the accompanying drawing, which illustrates the preferred embodimentof my invention,

Fig. l is a view, partly in side elevation, partly in vertical section,and partly broken away, of a pump provided with my improvement and shownmounted in a well.

Fig.2 is an enlarged vertical sectional view of a portion of my improveddrain shown mounted on a portion of a stand pipe which is shown partlyin elevation and partly in vertical section.

Similar reference characters designate similar parts in the diiferentviews.

1 designates an ordinary pump stand mounted on a platform 2, andsupporting the usual stand pipe 3, shown mounted in a well tubing ll,and provided with the usual pump cylinder 5.

The stand pipe 4; is provided above the cylinder 5 and at a suitabledistance below the surface of the ground with a drain opening 6, inwhich is fitted the lower end of a drain pipe 7 having an upwardly eX-tending portion 8, which is encircled by and spaced apart from avertical tube 9, the upper end of which is closed by a cap 10, in whichis mounted a valve ll, which may be of soft rubber, leather or othersuitable material, and which is adapted to seat upon and close the upperend of the vertical portion 8, of the drain pipe. A vertical manuallyreciprocative rod 12 extends `through an opening 13 in the platform andis attached at its lower end to the cap l0. rlhe upper end of the rod 12isprovided with an eye lei,k by means of which the rod 12 may be lifted,so as to lift the cap 10, valve 11, and tube. 9,`from the closedposition, shown in Fig. l, and in solid lines in Fig. 2, to the openposition shown in dotted lines in Fig. 2. l For supporting the rod 12,and the parts lifted by it in the open position, the stand l hasattachedy to it a hook 15, which is auapted to enter and support the eye14.

If desired, the stand pipe 3 may have secured to it a guide plate 16, inwhich the rod 12 is vertically slidable.

ln the normal operation of the invention, the rod 12, cap 10, and valve11 are in the closed position shown in Fig. l and in solid lines in Fig.2. ln freezing` weather, after thepump has been used, the rod l2 islifted to the open position and supported in said positionby the hook15. After pumping has ceased, the water in the stand pipe will bedrained, to the level of the upper end of the portion 8 of the drainpipe, the water so drained passing from the stand pipe through f thedrain pipe 7 8, and thence downwardly into the well tube 4, through thetube 9.

The drain pipe 7 8 is so disposed that the upper end thereof is farenough below the surface of the ground to be below the zone of freezingin the particular latitude in which the pump is located. The water whichremains in the stand pipe 3 and in the drain pipe 7 8 will, therefore,not be frozen.

When the pump is to be used, the rod 12 may be disengaged from the hook15 and lowered to the closed position shown in Fig.r

1 and in solid lines in Fig. 2. The valve l1 will then close the drainpipe 7 8, thereby preventing the discharge of water therethrough.

The drain pipe 7 8 with the use of the valve 11, may be made largeenough to quickly drain the stand pipe, so as to prevent liability offreezing even in very cold weather.

The tube 9 serves to retain the valve 11 in a position such that it willalways close the drain pipe when the valve is lowered to the closedposition. The tube 9 serves further as a weight to retain the valveseated, although the valve is subjected to the pressure of a relativelyhigh column of water. For this reason, the valve tube 9 is maderelatively long to obtain suiiicient weight to ,ing to any considerableeXtent. pipe is extended' upwardly a corresponding ,lengthY toaccommodate the long valve tube.u Y I ldo not limit my vinvention tothestruc1` overcome the pressure of the column of water in the pipe 3, whenthe valve is seated, and also as a guide toprevent the lvalveatilt: Thedrain and lowering saidvalve to respectively open' andclose the same,substantially as setitorth.

2.In ya pump drain, the combination with the stand pipe oii'a pump andthe stand supporting said pipe, the pipe having,l alateral opening fordrainage, and a drainpipe communicating with saidopening and'ha'ving anlupwardly, extending discharge portion, of a tube encircling and spacedapart from said portion, a cap mounted on the upper end of said tube, avalve in said cap adapted to 4,seat -upon andclose the upper end of saidportion, means attached to said cap for raisingl and lowering said valveto respectively open and close the latter, and means carriedbysaidnstand and adapted to engage and support said raisingand loweringmeans for 'holding the latter in the raised position, sub* stantially asset forth. i

3. In a pump drain, the combination with a stand of a pump and a standpipe supported thereby and having a lateral drain opening-.and a drainpipewcommunicating with said opening, and having an upwardly extendingjdischargeportion, of, a tube encircling and spaced aparti'rom saidportion andvertically adjustablq a cap closing the upper end ofsaid'tube, a valve in said cap arranged to close the upper end of saiddrain pipe, arod attachedat its lower endvto Vsaid cap and adapted tolift' the latter with said tube, the upper end of the rod having an eye,and means on said stand for engaging said eye for holding the rod andwith it the' tube and valve in the raised open substantially as setforth.

In testimony whereof I have signed my name to this speciiication.
